YSpecification of Letters Patent,

Application filed February 4, 1915, Serial VNo. 6,091. Renewed May 3, 191'?. Serial No. 166,276.

To all 'whom t may concern.'

Be it known that I, AXEL MoRcx, a citif zen of Sweden, and resident of the borough of Bronx, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Horseshoes, of which the following is a specication.

This invention relates to improvements in farriery,and is generally applicable to shoes worn by solipeds, of the genus Equus, i11- cluding the domestic horse and other solidungulate species of the same genus. In a more restricted sense, the invention has particular reference to a horseshoe provided with removable toe and heel calks.

One of the objects of the invention is to produce an improved horseshoe having separable calks, both at the toe and heel, that can be easily detached forv sharpening when dulled from any cause, or else replaced by,

newvones if too much worn out to be renovated.

A further object is to provide simple means, readily operable by horsemen or teamsters, whereby they will be enabled personally to take off the calks of a shoe with the aid of common tools, and securely reinsert or replace the same after removal.

Another object is the production of a shoe of the character set forth which shall be amenable to the ordinary process of drop,- forging, and therefore will not involve machine work or special fitting to complete it, thus alording a lowepriced article scarcely exceeding in cost that of the prevalent type of horseshoe with calks integrally formed.

Still another object is the provision of a comparatively light horseshoe, the weight whereof, including its detachable accessories, will closely approximate or not materially differ from that of the solidly calked shoe now in common use for the same purpose.

Other objects and advantages of the invention will become apparent as the speci.- cation proceeds. Vith the aforesaid objects in view, the invention consists of the improved combinations of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawing, wherein-f Figure 1 is a bottom plan view of ahorsef shoe constructed in accordance. with the present invention, parts thereof being shown in section, taken on theline 1,-1 of Fig. 3;

Fig. 2 is an outer edge viewof the forf ward part of the same, looking from the left-hand side of Fig. 1;

Fig. 3 is an inner edge view of one half of the shoe, with the calks and adjacent parts in section;

,Fig 4 is a transverse section on the line 4 4: of Fig. 3; and Y Fig. 5 is an end elevation of one of the heel calks pertaining to the invention, as the same appears previously to being given the form represented in Fig. 4.

In these views, the numeral 11 denotes the under or bottom face of the quarters or side portions of a horseshoe, having the customary fullering or creases 12, with nail holes 13.

Patented Dee. 18,1917.

At the front or toe part, the shoe is i formed on the under side with a straight or plane face 16, lying at a somewhat higher level than the bottom` edges 17 of the said quarters 11, in the said part of the shoe, which is made thicker or deeper fromthe top down, forward, as shown. In other words, the straight or plane face 16 is of substantially the same thickness as the rear portions of the quarters, but is bounded laterally by inclines 17, projecting Vdownwardly on each side thereof and forming opposite abutments, as indicated in Figs. 2 and Y f From the inner and outer edges, respectively 18- and 19, of the straight face 16, the front or toe part of the shoe' is beveled upwardly and inwardly in dovetail formation, as shown at 20, Fig. 3. The slanting faces 21 and 22 thereby formed are of simi'- lar inclination, excepting the upper margin of the, front face 21, which is offsetv forwardly as at 23, for a purpose lthat will hereinafter clearly appear.

The toe calk proper, designated by the reference numeral 26, is preferably formed integral with a plate or backing 27the full cross section whereof is shown shaded in Fig. 2 and is proportioned to fit snugly between the. straight inner edges of the beforementioned inclines 17, which serve to hold it positively against lateral displacement. Front and rear jaws 28, 29 extend upwardly from the saidv plate 27 and calk 26 thereunder, and are given the same inclination as that of the aforesaid faces 21, 22 of the front portion 20 of the shoe, barring the said margin or offset 23. The frontjaw 28 isi spaced away a certain distance from the frontl face 21, and has its in ner surface 30 beveled off,

as seen in Fig. 1, with relation to the latter* named face. A wedge key 31, having its outer side conforming to the Obliquity of the surface 30, is driven into the space intervening between the latter and the face 2l. of the part 20. rEhe upper fiat surface of the plate 27 and the inner' face of the rear jaw 29 are thereby drawn j forcibly into contactr with the underside or straight face 16 and the rear edge 22, respectively, of the front part. 20 of the shoe. y

The breadth of the said key 31, measured from front to rear, and the drawing Vaction thereby exerted hold the front jaw 2S of the plate 27 from sagging or slipping down. T he thin end or point 32 of the rey is bent over the edge of the jaw 28, when it has been driven in as far as it will go, to preclude disassociation of the conjoined parts. The upper inner edge of the key finds lodgment in the obtuse angle formed by the inclined front face 21 of the dovetail section 20 of the shoe and the vertical edge 23 of the latter, and is thereby prevented from creeping up and out of place.

The upper portion of the front jaw 28 may be carried up above the top face 33, to form a removable clip 34, which can be hammered to conform to the point of a horses hoof, analogously to what was done heretofore with the ordinary horseshoe. As indicated particularly in Figs. 1 and 4, the rear end of the shoe is dovetailed in two directions, to wit,` longitudinally of the quarters, with the taper increasing rearward, as at 37, and transversely, after the manner of the front section 20, that is with upwardly and inwardly beveled sides 38, 39, the eX- terior one of which is formed with a straight portion 40 similar to the tiattened margin 23 of the said front section 2O and Provided for a like purpose.

A removable heel calk 4 depending from a plate or backing 42, is attached to the rear end 37 ofthe shoe. The plate or backing 42 is formed with jaws 43 and 44, the latter of which is on the outside of the shoe and spaced from the said beveled side 38, so that a wedge key 45 can be driven therebetween. rl`he forced insertion of this key draws the upper surface 46 of the heel-calk plate 42, as also the jaw 43 thereof, solidly against the under side 11 of the shoe and the beveled side 39 of the rear section 47, respectively. To hold the key from working out, the end- 48 thereof may be bent over the adjoining edge of the jaw 44, as represented in Fig. 1.

Longitudinal displacement of the rear calk-plate 42,7relatively to the end section 47, is guarded against by forming in the latter a recess or cavity 49, adapted to be engaged by a ridge or protuberance 50, struck up from the inner face 46 of the said plate 42. j

lThe said heel calk is drop-forged with the nasa/as@c jaws 43, 44 thereof straight or perpendicular to the ,face 46, as represented in Fig. 5, so that itsseveral angles and corners will readilv leave the die in which it is made. The

Vheel calk having been formed in the manner indicated, the jaws thereof are subsequently forced to'assume the shape illustrated in Fig. 4. It is understoodthat the narrowest opening is left between the lips of these jaws to permit the heel calk to be slipped over the flaring` base of the shoe section 47. f

Although no separateV illustration of the toe-calk has been given, it is obvious that the same process is followed in forming the slanting jaws of the latter as for those of the heel calk. fr

1t will further be understood that, notwithstanding thesquare heel calk 53 pertaining to the inner half of the Vshoe has been shown asbeing formed solid therewith, obviously it is within the scope ofthe invention to make this calk on the same order as the sharp-pointed outer heel-calk 41.

Having described my invention, what I desire to secure by Letters Patent and claim, 1s:-

1. A horseshoe having a toe portion formed with a substantially plane under face, a detachable calk-bearing plate lsecured torsaid toe portion, Vand abutments by the longitudinal sides of said plate inclined away from the same in opposite directions toward the bottom face of the shoes side portions. f Y

2. A horseshoe including a toe with oppositely inclined portions on the under sido thereof, a dovetailed section of less thickness intermediate of .sa-id inclined portions, a calk-bearing plate, and'clasping means of corresponding shape to said section serving to hold said'plate thereon infirm position.

3. A horseshoe comprising a dovetailed member having a marginal projection on the frontside thereof, a calk-bearing plate provided with jaws set at inclines conforming to the opposite front and rear sides of said member, and a wedge key insertible between one of said jaws and the adjacent side of the member under said marginal projection. 4. A horseshoe comprising an externally dovetailed toe portion, a calk-bearing plate embracing the same, jaws on said platerising on opposite sides of said toe portion with their inner faces inclined to correspond with said toe portion, a clip on one of said jaws, and means acting against the outside face of the toe portion operating to draw the other jaw in contact with the inner face thereof.

5. A horseshoe having a portion formed with anapproximately straight under face, inclined edges extending upwardly from the front and rear thereof, abutments depending from the sides of said portion, and a. calk-bearing plate removably received between said abutments and clasping said inclined edges.

6. A horseshoe including a flat portion in its under side, oppositely tapered facesex-v tending upwardly from two edges of said fiat portion, substantially perpendicular faces constituting abutment-s depending from the other edges of said portion, a detachable calk-bearing plate having a plane upper part with inclined jaws at the ends thereof'and provided with straight side edges, the latter being received between said abutments, and means for drawing the upper part of said plate against the under side of the fiat portion on the shoe, with a jaw in contact with one of the tapered faces and the other jaw spaced away from the other tapered face.

7. A horseshoe comprising a substantially plane portion formed on the under side thereof, inwardly slanting faces extending upwardly from opposed edges of said plane portion, one of said faces having a forwardly offset marginal projection, abutments depending frorn adjacent edges of said portion, a calk-bearing plate including a flat upper part carrying bevel-ed jaws removably received between said abutments, and a wedge key driven intermediately of one jaw and one of the slanting faces so as to draw the flat part of the plate against the plane portion' of the shoe and with the other jaw in contact with the oppositely slanting face, said key having one edge lodged against said marginal projection to prevent it from working out.

Signed at the borough of Manhattan in the county of New York and State of New York this 23rd day of January A. D. 1915.
